Sims 2 university installation?

I already have sims 2 dvd version. then i downloaded sims 2 university cd version from mediafire. i installed it by mounting the two image files with daemon tools. after it goes 100%, the updater opens and asks for the sims 2 disk 4. i have sims 2 dvd so this there is no disk 4. i cancelled it and the installation terminates. is there a way to install sims 2 university cd version even if sims 2 is dvd?
